- Available in sizes 4.76mm up to and including 104.78mm
- Available as ‘Hard Drawn’ straight lengths, (BQ) ‘Bendable Quality’ straight lengths or, annealed coils and annealed layer wound packs.
- Pink capped tube has been specifically designed to meet the requirements of R410A and R32 high pressure applications. Identifiable by the pink caps used to protect the internal cleanliness of the tube and a continuous ink mark “KEMBLA AUSTRALIA AS/NZS1571 (DIAMETER) X (WALL THICKNESS) HIGH PRESSURE REFRIGERATION TUBE”
- Straight lengths available in 6 metre and 5.8 metre lengths (export only)
- Half hard or bendable quality straight lengths can be bent using bending tools without applying additional heat.
- Copper tubes and fittings can be successfully joined by silver brazing or flaring
- Silver brazing shall be carried out by professional tradespersons using brazing principles and safety procedures in accordance with AS HB40.
- The use of 15% silver solder is recommended when brazing tube or fittings for use with R410A or other high pressure refrigerants. A proprietary silver brazing flux shall be used.
- R410A has a 60% higher operating pressure than R22 thus requiring a thicker wall copper tube and significantly stronger R410A rated copper fittings. The minimum allowable tube wall thickness shall be 0.81mm (outside diameter size dependant).
